            <code class="function">glGenTextures</code> returns <em class="parameter"><code>n</code></em> texture names in <em class="parameter"><code>textures</code></em>.
            There is no guarantee that the names form a contiguous set of integers;
            however, it is guaranteed that none of the returned names was in use
            immediately before the call to <code class="function">glGenTextures</code>.
        </p><p>
            The generated textures have no dimensionality; they assume the dimensionality
            of the texture target to which they are first bound
            (see <a href="glBindTexture"><span class="citerefentry"><span class="refentrytitle">glBindTexture</span></span></a>).
        </p><p>
            Texture names returned by a call to <code class="function">glGenTextures</code> are not returned by
            subsequent calls, unless they are first deleted with
            <a href="glDeleteTextures"><span class="citerefentry"><span class="refentrytitle">glDeleteTextures</span></span></a>.
